Ngā mea e ruaNgā panera PIRmengā panera rokiroki makaririe pā ana ki ngā rauemi whakamarumaru mahi-teitei. Ko te rerekētanga matua kei roto i te rauemi me te whakanui i te mahi: Ko ngā panera PIR (ngā panera polyisocyanurate) he whakahoutanga matatau ake o te polyurethane (PUR), he pai te ātete mura, he ātete pāmahana teitei (tae atu ki te 200℃ me runga ake), me te iti o te mimiti makuku (he iti iho i te PUR). Koinei te whiringa tuatahi mō te hanga whare rokiroki makariri e hiahiatia ana, ngā whare tukatuka kai, me ētahi atu whare. Ko ngā "panera rokiroki makariri" e pā ana ki ngā rauemi whakamarumaru e whakamahia ana i roto i te rokiroki makariri, ka taea te PIR, PUR, XPS, me ētahi atu. Nā tōna mahi whānui, kua noho te PIR hei kaupapa matua o ngā mea papai hou.ngā panera rokiroki makariri.
Ngā Āhuatanga Matua o te Poari PIR (Polyisocyanurate):
Ātete Ahi Pai Rawa: Mā te whakanui ake i te kukū o te mowhiti isocyanate, ka nui ake tōna ātete ahi i tō te papa PUR noa, ka eke ki te whakatauranga ahi B1.
Ārai Wera Pai Rawa: He tino iti te kawe wera (≤0.023 W/mK), ā, he tino pai te whai huatanga o te ārai wera.
Ātete ki te Pāmahana Teitei: Ka taea e te whakamahinga roa te tu atu i ngā pāmahana neke atu i te 150℃, tae atu ki te 205℃, he pai mō ngā taiao pāmahana teitei.
Iti te mimiti wai: He tino iti te tere mimiti wai, e ārai ana i te urunga mai o te makuku me te pupuri i te mahi whakamarumaru.
Kaha Teitei: He matotoru te matotoru, he hanganga pumau, e whakapakari ana i te kaha o te whare.
He pai mō te taiao: Kore CFC.
Ngā Paewhiri Rokiroki Matao:
Ariā Whānui: E pā ana ki ngā panera hanawiti katoa e whakamahia ana i roto i te hanganga o ngā whare rokiroki makariri; ko te mahi matua ko te whakamahana me te hiri.
Ngā Rauemi Kanorau: Haunga te papa PIR matua, kei roto hoki ko te PUR (polyurethane), te XPS (polystyrene extruded), me ētahi atu.
Arotahi ki te Mahi: Ka tīpakohia ngā rauemi matua rerekē i runga anō i ngā whakaritenga pāmahana o te rokiroki makariri.
Ngā Paewhiri PIR me ngā Paewhiri Rokiroki Matao PUR Auau
Ātete Ahi: PIR > PUR
Ātete Pāmahana: PIR (-196℃ + 205℃) > PUR (-185℃ + 110℃)
Te mimiti wai: PIR (<1%)< PUR (2.5%~3%)
Kiato: PIR (40-45 kg/m³) > PUR (38-40 kg/m³)
Utu: Ko te PIR he nui ake i te PUR.
Whakarāpopototanga
Ko ngā panera PIR he tohu mō ngā panera rokiroki makariri mahi-teitei, he mea tino pai mō ngā umanga mekameka makariri hou me ngā ahumahi tukatuka kai me ngā whakaritenga pakari mō te ātete ahi, te ātete pāmahana teitei, me te mimiti makuku iti. He otinga whakamarumaru haumaru ake, he pono ake hoki ēnei i ngā panera rūma makariri PU tuku iho.
